BAG-SEAL.

To all whom it may concern Be it known that I, VVmrnnn "MUDGE Bnoons, acitizen of the United States of America, and a resident of East Orange,in the State of New Jersey, have invented a new and useful Improvementin Bag-Seals, of which the following is a specification.

This invention relates to means for securely fastening and sealing thenecks of bags of textile fabric or other articles with cords so as toinsure the detection of any tampering therewith.

The present improvement is primarily ad ditional to my patent datedJanuary 26, 1915 No. 1,126,37 6, that is to saythe im proved bag sealpreferably has in combina tion aloop-forming cord adapted to embrace theneck of the bag and a compressible lead seal part having threading holesthrough which the ends of the cord protrude sufliciently to be pulledtight by some suitable means such as shown in my seal press cordtightening device, copending application Serial No. 28,064, said sealpart being further constructed with projections on one side adapted tointeract with recesses in theface of one of the dies, also preferably acentral threading hole through which the two ends of the cord protrudeand side holes parallel with said central hole to provide for a doubleloop of the cord, together with a metallic pin element combined withsuch loop-forming cord and apertured seal as shown in said patent.

The leading objects of this invention are to make sure of theinterrelation of the cord loops and the metallic pin element so as toinsure a permanent seal fastening and to provide means for firmly andtightly placing the said pin element into its proper position in thesealing operation.

A sheet of drawings accompanies this specification as part thereof, inwhich like reference characters refer to like parts throughout.

Figure 1 is a perspective view of the wire member of said pin element ofthe improved bag seal; Fig. 2 is a perspective view of the same providedwith its pushing and pulling knob; Fig. 3 is a side view of the sameshowing the novel cord hole; Figs. 4 and 5 are perspective views of themain seal part showing its respective sides; Fig. 6 is a sectional viewof said main seal part threaded with the loop-forming cord and with thepin Specification of Letters Patent.

element in position upon one loop, preparaand the pin element insertedin the bag neck preliminary to final tightening and sealing; Fig. 8 is aside view of the neck of a bag sealed with the improved device.

The improved press fastenable seal is composed of a neck pinning elementa, a main seal part b and a loop forming cord 0. Said neck-pinningelement isin turn composed of two members 1 and 2, the first of which isa piece of moderately hard wire, Fig. 1, preferably iron, having itsheel end 3 crimped and its other end pointed. Upon the crimped end ofthis wire said member 2, which is a pushing, pulling and loop engagingknob provided with a transverse hole 5 through which the cord is passed,preferably and conveniently of lead is cast fast. A. flat thumb-engagingend 4 facilitates the preliminary pushing of this pin through the foldsof the bag neck and same can be embossed if desired. This element may ofcourse be constructed in any other desirable or convenient way of onepiece or more, the essential features being the pin shank and knob headhaving a transverse hole for the reception of the loop cord. The sealpart b is a compressible casting of lead having a double width centralthreading hole 6, side holes 7 S, parallel'therewith and one or moretransverse projections 9, 10, Fig. & on one side to interlock with acorrespondingly recessed bed die in the seal press to preventdisplacement in pulling the cords by the seal press cord tightener. Thecord 0 is preferably a hard twine which is first passed through the holein the head of the pin element and then so threaded through thehole's ofthe main seal part as to produce two sealing loops with the pin threadedupon one of them, as shown in Fig. 6. The loops are first placed overthe bag neck and the pin thrust through the folds and then through thecentral hole of the seal along with the two ends of the cord alreadythreaded therethrough as shown in Fig. 7. The seal is then placed in aseal press and the cord ends drawn by means of the cord-tightenerattachment to the desired tension thus compressing the loops about theneck of the bag and at the same time firmly pressing home the pinelement. The seal is then compresed and the operationis completed.

With the completed seal fastening it is im- 1 possible to remove the pinelement Without destroying the cord .loop upon which it is threaded andWithoutremoving the pin ele-. ment it is impossible to slip thefastening" loops from the, neck of thebag. Furthermore all uncertaintyisremoved as to the proper engagement of the loops With the pin elementwhich is made positive.

Having thus fully disclosed my invention lclai'mz' i a 1. In"combinationwith a loop-forming cord and a compressible seal oart, thelatter G'opjbsj ofthis patent may be obtained for having means includinga central threading hole to engage. said corda neck-pinning elementadapted to penetrate the neck of a bag and to extend through saidcentral hole insaid sealpart and having a head provided wit'h'atransverse hole adapted to receive the loop cord and to be threaded uponone or" the sealing loops, 1 whereby in the sealing operation said pinelement is drawn by the cords through the bag neck and seal part Whereit is secured by the final compression of the latter part.

A press-fastenableseal having in combination a compressiblesealpart provided With three parallel threading holes and means forpreventing the displacement of said seal When between the dies of a sealpress, a loop forming cord adapted to be threadedthroughsaid seal parttoform two adjacent sealing loops and a metallic pin element having apointed shank. adapted to penetrate the neck of a bag and then passthrough the central hole of the seal part adapted to receive said loopcord and to be threaded upon one, of said sealing loops,-

whereby in thesealing operation said pin element is drawn bythe cordsthrough the I bag neck and seal part where it is secured by the finalcompression of the latter part, all substantially as hereinbefore setforth.
